Seminiferous tubules are lined by

Explanation

Seminiferous tubules are present in the lobules of testes. Each seminiferous tubule is lined by the germinal epithelium which consists of undifferentiated male geim cells called spermatogonial mother cells and .nourishing cells. called .Sertoli cells! The spermatogenia produce primary spermatocytes which undergo meoitic division finally leading to the formation of Spermatozoa or sperms (spermatogenesis).

Sertoli cells provide nutrition to spermatozoa and produce a hormone .inhibin. which inhibits the secretion of FSH. The regions outside the seminiferous tubules called interstitial spaces, contain Leydig cells. Leydig cells produce androgens, mainly Testosterone that controls the development of secondary sexual characters and spermatogenesis. The seminiferous tubules open into .vasa efferential through the .rete testis.. .
